The Freezing Behavior of Particle Mixtures
Associate Professor of Chemistry and Mechanical Engineering Ryan Sullivan published a paper in the journal Atmospheric Chemistry and Physics titled “A new multi-component heterogeneous ice nucleation model and its application to Snomax bacterial particles and a Snomax-illite mineral particle mixture."
In this paper, Sullivan and his students— Mechanical Engineering graduate student, Hassan Beydoun, and Chemistry graduate student, Michael Polen—investigate the freezing behavior of biological ice nucleating particles (INP) mixed with mineral dust particles to examine how these mixtures could potentially impact the abundance of ice nucleating particle surfaces in the atmosphere.
